+a logical monitor on top of another monitor or
+cinerama, an epimonitor. The epimonitor is position

+for example start a single-monitor full screen game
+but keep a part, for example the status bar with

+There are two forms of logical monitors: cineramas
+and epimonitor. A cinerama combines monitors into
+one monitor. Epimonitors takes a subset of a single
+monitor. Similar to having two monitors with overlaping
+output,@footnote{For example a monitor with mode--position
+1600x1200+0+0 and a monitor with mode--position
+1600x1200+800+600.} An epimonitor overlaps with another
+monitor, but only with that monitor and cannot be outside
+it even partially. But it does not need to cover it
+completely. This allows you to put a full-screen window
+on the epimonitor and thus only partially cover the
+physical monitor; for example keeping the clock visible.
+
+Epimonitors do not need to be placed inside a physical
+monitor. They can be placed on top of a logical monitor
+too. Putting an epimonitor on top of a cineramma lets
+you create a logical monitor that covers multiple
+monitors partially.
